Position information identification device for cleaning robot

Abstract

In the conventional cleaning robot, by mainly using each supersonic waves sensor having a sensing range as +-30 DEG in consideration of an appropriate sensitivity, when four supersonic waves sensors are installed at a cleaner main body, a sensing range as 240 DEG is obtained, and accordingly it is impossible to observe surroundings of the cleaner thoroughly. In order to solve the above-mentioned problem, a position information recognition apparatus for a cleaning robot in accordance with the present invention includes a fixed plate installed at a cleaner main body; a main motor fixedly installed at the fixed plate in order to generate a rotational force; a rotational cylinder combined with a rotational axis of the main motor so as to be rotated at a certain angle; and plural position information sensors installed at the rotational cylinder at a certain angle in order to sense surroundings. By installing several supersonic waves sensors performable left / right rotation at regular intervals, observation region can be greatly increased, and accordingly it is possible to improve efficiency by eliminating unnecessary rotational motion of the cleaner main body in position recognition and distance compensation.

Description

Technical field [0001] The present invention relates to a position information recognition device for a cleaning robot, and more particularly, to a position information recognition device for a cleaning robot that can observe the surrounding environment of the cleaning robot 360° by rotating a sensor at a certain angle. Background technique [0002] Generally, an automatic mobile cleaner (hereinafter referred to as a cleaning robot) performs cleaning work while it is moving. When the rechargeable battery power is exhausted, it will move to the charging position by itself, charge it, and return to the cleaning position after charging. Clean up again. [0003] In order to perform cleaning and charging while moving back and forth in the cleaning area, a conventional cleaning robot includes a cleaner main body 1 with a fan motor, a suction pipe, a filter, etc.; a plurality of rotatably installed on the bottom surface of the cleaner main body 1 And move the driving wheels 2 of the cle...

AI Technical Summary

Problems solved by technology

[0006] However, as mentioned above, in the conventional cleaning robot, because the appropriate sensitivity is considered, a sensor with a detection range of ±30° is mainly used as the ultrasonic sensor 3, and when four ultrasonic sensors 3 are installed on the cleaner main body 1, the detection The range is only 240°, so cannot adequately see around the cleaner
